Tuesday's ruling by a federal judge, which said Kentucky's ban violated the Equal Protection Clause of the U.S. Constitution, was put on hold because similar cases from other states are being heard by a federal appeals court. It's unclear when Kentucky may begin issuing marriage licenses.

It's a conundrum that's played out nationwide in the fight to legalize gay marriage: The rulings mark a significant shift as rulings in favor of gay marriage pile up, but confusion emerges as to when those marriages can begin. In Wisconsin, for example, same-sex couples had a window of about a week to get married before a judge ordered officials to stop issuing them marriage licenses. And in Utah, more than 1,000 couples who rushed to marry after a judge overturned that state's ban will have to keep waiting for many legal benefits of being married.

For now, lead plaintiff Timothy Love of Louisville said he will celebrate the latest victory with his partner of 34 years, 55-year-old Larry Ysunza.

"It's a win and we're going to win in the end. Now, the headline is 'Love Wins,'" Love said Tuesday afternoon.

He also said he anticipated a wait: "We all probably have to wait until the Supreme Court makes its decision" on gay marriage bans across the nation.

In the Kentucky case, U.S. District Judge John G. Heyburn II concluded that the state's prohibition on same-sex couples being wed violates the Equal Protection Clause by treating gay couples differently than straight couples. Heyburn previously struck down Kentucky's ban on recognizing same-sex marriages from other states and countries, but he put the implementation of that ruling on hold.

"Sometimes, by upholding equal rights for a few, courts necessarily must require others to forebear some prior conduct or restrain some personal instinct," Heyburn wrote. "Here, that would not seem to be the case. Assuring equal protection for same-sex couples does not diminish the freedom of others to any degree."

Kentucky Gov. Steve Beshear said the state will appeal Heyburn's decision.

The U.S. 6th Circuit Court of Appeals has scheduled arguments on rulings from Ohio, Michigan, Kentucky and Tennessee in a single session on Aug. 6. Although the cases are unique, each deals with whether statewide gay marriage bans violate the Constitution. It's not yet clear if Kentucky's appeal of the latest decision will also be heard in that session.

Plaintiffs' attorney Dan Canon said the appeals court decision would likely determine the fate of Kentucky's ban, regardless of any move by the governor.

Heyburn noted that every federal court to consider a same-sex marriage ban has found it unconstitutional. Gay rights activists have won 18 cases in federal and state courts since the U.S. Supreme Court in June 2013 struck down a key part of the federal Defense of Marriage Act that denied to legally married same-sex couples a range of benefits generally available to married heterosexuals.

Heyburn, an appointee of President George H.W. Bush, dismissed the governor's argument that Kentucky's prohibition encouraged, promoted and supported relationships among people who have the "natural ability to procreate" and a stable birth rate ensures the state's long-term economic stability.

"These arguments are not those of serious people," Heyburn wrote.

Martin Cothran, a senior policy analyst with the Family Foundation of Kentucky, said Heyburn erred in considering same-sex couples "politically powerless" in today's society.

"We're thinking this judge needs to get out a little more," Cothran said. "Or maybe he could just subscribe to a newspaper or possibly turn on the television, where he could see just how politically powerless are the people whose political power helped produce this decision."

Evan Wolfson, founder of Freedom to Marry, a group backing same-sex marriage, said the ruling shows the public is ready to remove the legal bans put in place in many states.

"It is wrong for the government to deny same-sex couples the freedom to marry the person they love; a freedom that is part of every American's liberty and pursuit of happiness," Wolfson said.
